PIPE-JOINT.

' Application ined time 6,1903. serial No. 160,302. (Nd model.)

To all whom it may concern:

Be it known that I, HERMAN STIER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, haveA vide a system of joints which may be madey 'positively air and liquid tight at small cost and with a minimum expenditure of time and labor.

Another object of the invention is to provide a connection which shall be yielding and permit of the shifting ofthe relative positions of the connected pipes. l

The invention consists generally in an inclosing box for the ends kof adjacent pipes and means for securing said box and pipes together. 4.

The invention further consists inthe combination, with a plurality of pipes closed at their ends, of a box inclosing said ends and constituting a conduit therebetween and suitable pipe-openings into said box; and the iAnvention further consists in the novel details of construction hereinafter referred to in detail, illustrated in the drawings, and incorpoed apertures 13 in the end walls 3. the heads of the bolts and the box 6 gaskets lateral apertures 4, and a ring or flange 5 at the connecting-joint. The latterconsists of va preferably box-form structure 6, having pipe-apertures 7 are small bolt-holes 1l for the threaded bolts l2, engaging screw-thread- Between 14 are placed, for which suitable counterbores in the box are also provided, as shown.

From the foregoing description the operation of my invention will bey obvious, each box 6 providing a joint for the adjacent ends -of pipes 2 2 as well as a conduit between the apertures 4. The bolts 12 exert a direct pull todraw the rings 5 tightlylagainst the gaskets and at the same time pack the bolt-openings tightly against leakage. The countersunk apertures for the gaskets prevent the latter from spreading and facilitate a perfectly tight joint without the necessity of tightening' the bolts very hard. The simple `bolt-and-nut engagement between the ends of pipes and the boxes is at'once both very effect- `ive and lsimple and easyv in its' ,.operation.` A

series ofpipes vmay be quickly-.assembled or taken apart by unskilled help, whereas in the more common constructions the joints are usually such as to require experienced or expert workmanship. My invention also provides for great iiexibility in a circulatory system, and the series of pipes may be relatively shifted in vertical or parallel planes while in operation as liuid-conduits without endangering the integrity of the jointy or joints..

Inpractice it is often foundv necessary to twist the joints in order to'change the p ositions of the pipes, and my invention is highly susceptible to such operations. The boxes 6 embody the very simplest possible form. of construction. They may be cast at a smallv cost and do not require a nice or exact adjustment, the powerful and positive engagement of pipesand bolts, in combination with the gaskets, being adapted to compensate for slight 'each of *which has an end wall 3, a series of Too irregularities of surface. Again, no `frictional or twisting strain is imposed upon the gaskets l() in effecting the coupling, as the latter are made tight through straight pressure as opposed to all forms of joints where the gasket is interposed between parts which must be turned upon or relatively to each other in order to tighten the engaging threads.

As illustrated in Fig. 4C, other means than the threaded bolt 12 in engagement with the wall 3 may be provided for drawing the parts togethergas, for instance, a pin or rod 2, extending through opposite apertures 4, similar to apertures 4, in which case the said threaded portion would engage a threaded aperture l5 in each of the rods 2, which would take the places of the closed ends 3 of the pipes. In that event the pipe could be open at its end, as shown in Fig. et, instead of having the wall 3 and would require only two apertures e or suiiicient to support the end of the rod or pin. I therefore do not wish to confine my invention to the exact method shown for drawing the box against the gasket 10 and iange or ring 5, this feature being' susceptible of numerous modiiications without departing from the spirit of my invention.

Having thus described my invention, I ciaim as new and desire to secure-by Letters PatentA l. The combination of a plurality of hollow boxes movable angularly with relation to each other in two parallel planes, with a series of parallel pipes connecting said boxes and swiveljoints for securing said boxes and pipes together constructed and arranged to permit the boxes to be moved relatively to the pipes in planes at right angles to the axes of the pipes.

2. rI`he combination of two parallel series of hollow boxes, each series of boxes arranged in substantially the same plane, and movable angularly with relation to each other, with a plurality of parallel pipes communicating with the interior ot' said boxes, each pipe communicating with the opposite ends of two boxes in both of said parallel series and means for securing said pipes to said boxes steamtight and rotatively relatively to each other, all of said boxes and pipes forming one continuous conduit.

3. The combination of two series of hollow boxes movable angularly in one plane and placed end to end in each series and the adjacent ends or' each series occupying substantially a plane intersecting the middle portion of a box in the other series, with a plurality ot pipes connecting said boxes, said pipes being arranged in pairs, each pair opening into the opposite ends oi each box ol one series of boxes and into adjacent ends of dill'erent boxes in the other series of boxes.

4. rI`he combination of a plurality of hollow boxes arranged in one plane with a similar series of boxes arranged in another plane, a series of parallel straight pipes between said boxes opening into the opposite ends olt each box in one plane and into the adjacent ends of separate boxes in the other plane, and means for securing said boxes and pipes together to form one continuous conduit, whereby said pipes may be moved parallel and said boxes moved angularly with relation to each other, each of said series of boxes providing concentric conduits at right angles to the pipeconduits.

5. The combination of hollow boxes and a series of parallel pipes arranged in pairs.I each pair coupled together through one ol said boxes, and each pipe ot said pair having its opposite end similarly coupled to a separate box communicating with an adjacent pipe, with means Jfor connecting all of said pipes to their respective boxes whereby said pairs of pipes may be moved parallel relatively to each other.

6. The combination of a series of parallel pipes arranged in pairs, a series ol boxes each connecting a pair of pipes at one end, said boxes movable angularly with relation to each other in a single plane,with a similar series oi boxes each connecting` a pipe of one pair to a pipe otl another pair at their opposite ends, means for rotatively securing the ends of said pipes in said boxes, said ends projecting into said boxes and having a plurality ol holes communicating with the interior ot said boxes.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.

HERMAN S'IIER.
